This series adds ARM support to the XenBusDxe driver. It consists of
an implementation of the hypercall interface, changes to work around
the lack of PCI, and a bugfix. Finally, patch #5 wires it up to the
VirtFdtDxe driver that is used in the ARM VM port, and will also be
used by the Xen/ARM targeted port.
Note that this is build tested only, both on ARM and x86. I am struggling
to get access to suitable ARM hardware, and running Xen on my Macbook has
proven to be a discouraging experience, hence the 'RFC' status of this patches.
If anyone feels adventurous and bored, it would be good to know that I did not
break x86 support in this series, so any testing is highly appreciated.

Ovmf/Xen: move arch specific hypercall implementation to
XenHypercallLib
Ovmf/Xen: allow non-PCI usage of XenBusDxe
Ovmf/Xen: add ARM and AArch64 support to XenBusDxe
Ovmf/Xen: fix pointer to int cast in XenBusDxe
